Equestria's most intrepid heroes, The Elements of Harmony, set off on a routine quest to plunder a dungeon full of Diamond Dogs. But they may have bitten off more than they can chew when an old enemy reappears...

Contains M/F, Monster Rape, "Bad-End", and an "It was all someone's D&D campaign" ending so none of this actually happened. But it's MLP fanfic, so it really never happened either way.
